The Use of a Preserved Dural(LYODURA(R)) in the Congenital Ptosis Surgery

ABSTRACT

LYODURA(R) is commercial name of a cleaned, desantigenized, desenzymatised, rendered free of pyogenics, sterilized by gamma rays, and lyophilized dura. Frontalis suspension with LYODURA(R) was performed to a total of 16 patients(21 lids) of congenital ptosis with levator muscle function of 3mm or less in the ptbtic lid. The follow-up period ranged from 2 to 39 weeks with a mean of 19.6 weeks. Postoperative lid levels were judged good, fair, and poor. Good results occurred in 12 of 21 procedures(57.1 %) and fair results in 6 of 21 prqcedures(28.6%). The summation of these two indicates an overall satisfactory result of 18 of 21 cases(85.7%).
